ios - 快速插入新的静态单元格表​​ View

Question

想要添加新的单元格。我怎样才能做到这一点？请帮忙!我尝试一下

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if section == 1 {
        return 3 + eventDates.count
    } else {
        return super.tableView(tableView, numberOfRowsInSection: section)
    }
}


override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    if (indexPath.section == 0 && indexPath.row == 1) {
        eventDaysVisible = !eventDaysVisible
        tableView.reloadData()

        tableView.insertRowsAtIndexPaths([NSIndexPath(forRow: eventDates.count + 3, inSection: 0)], withRowAnimation: .Automatic)
        tableView.reloadData()
    }

    for day in eventDates {
        print("OBJ: \(day)")
    }

    tableView.deselectRowAtIndexPath(indexPath, animated: true)
}

我有 3 个静态单元格，如果我切换按钮，则需要在第一个单元格之后插入新单元格。

var eventdates =  Friday, Saturday, Sunday

希望你能帮助我。

import UIKit

class ViewController: UIViewController {

    var cellCount = 1

    @IBOutlet weak var tableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}


extension ViewController:UITableViewDataSource {

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        return cellCount
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = UITableViewCell()

        cell.backgroundColor = UIColor.grayColor()

        return cell

    }

    func tableView(tableView: UITableView, shouldHighlightRowAtIndexPath indexPath: NSIndexPath) -> Bool {
        return true
    }

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        let eventDates = ["1", "2", "3"]

        var indexPathsArray = [NSIndexPath]()

        for rowCount in 0 ..< eventDates.count {
            indexPathsArray.append(NSIndexPath(forRow: rowCount, inSection: 0))
            cellCount += 1
        }

        tableView.beginUpdates()
        tableView.insertRowsAtIndexPaths(indexPathsArray, withRowAnimation: .Automatic)
        tableView.endUpdates()

        tableView.deselectRowAtIndexPath(indexPath, animated: true)
    }
